History of Glock Sights

Initially, Glock pistols came equipped with a basic set of sights, which included a simple notch rear sight and a front post. Over the years, due to user feedback and the evolution of shooting practices, Glock's standard sights have been the subject of praise and critique. Upgrades and alternatives have become widely available, facilitating customization for diverse shooter needs.

Anatomy of Glock Sights

Glock sights are composed of two main components: the front sight, positioned on the barrel's end, and the rear sight, mounted on the slide's rear. The front sight is designed to be aligned with the rear sight to aid in proper targeting. Glock sights may come in various configurations, with certain sights offering white dots or luminescent paint to aid in sight visibility.

Types of Glock Sights

Glock sights are available in several types, each catering to different lighting conditions and user preferences:

  • Iron Sights: The classic and durable no-frills option that relies on metal construction without illumination.
  • Night Sights: Usually contain tritium, a radioactive material that glows in low lighting.
  • Fiber Optic Sights: Utilize fiber optics to channel ambient light, enhancing visibility in daytime conditions.
  • Luminescent Sights are often painted with photoluminescent paint that gets charged by exposure to light and glows in reduced lighting.

Material and Durability

Glock sights are commonly crafted from:

  • Steel: High durability and resistance to impact.
  • Aluminum: Lightweight with satisfactory strength.
  • Polymer: As part of Glock's original design, it offers sufficient durability and is very lightweight.

Durability is critical as sights must withstand the recoil and wear from regular use. Steel sights are known for their robustness, while aluminum provides a good balance between durability and weight. Fiber optics, though more fragile, offer excellent visibility. With tritium inserts, night sights are designed to last years without requiring external light sources.

Selecting the Best Glock Sights

Choosing the correct Glock sights involves considering various factors that affect performance, including precision, visibility, and compatibility with specific Glock models.

Factors for Selection

When selecting Glock sights, the primary considerations should include target acquisition, visibility, and compatibility with your Glock model. Durability and ease of installation are also crucial. For competitive shooters, the sights' precision and contrast can significantly impact their scoring.

Night Sight Options

Tritium night sights remain popular for low-light conditions as they provide self-illuminating capabilities. These sights emit a glow using tritium, a radioactive form of hydrogen, enhancing accuracy in dim environments. The HiViz Litewave H3 combines tritium with Litepipe technology for day/night visibility.

Fiber Optic Sights Advantages

Fiber optic sights offer excellent visibility in bright conditions, directing ambient light to the sight dots. Models like the Ameriglo Spartan and Viking Tactics provide bright, contrasting colors, aiding in quick target acquisition. They are preferred for their high contrast and ease of use during daylight hours.

Red Dot and Co-Witnessing

Integrating red dot sights with suppressor height options allows for co-witnessing, enabling users to align iron sights with the red dot as a backup should the red dot fail. Co-witnessing is essential for tactical scenarios, providing a reliable sighting alternative.

Aftermarket vs. Factory Sights

Aftermarket sights often offer significant improvements in accuracy and visibility over factory sights. Models like XS DXT2 Big Dot and Trijicon Suppressor/Optic Height Sights offer superior target acquisition in various color variations. They can cater to specific needs, such as suppressor height requirements or personal preferences for sight pictures.

Installing and Maintaining Glock Sights

When it comes to enhancing the accuracy and speed of a Glock, installing high-quality sights and maintaining them properly is crucial. A well-installed sight ensures a clear sight picture, while regular maintenance guarantees lasting performance and reliability.

Proper Installation Techniques

Proper installation of Glock sights is essential for a precise sight picture. One should avoid installing sights without adequate tools, which could damage the firearm's sight. Attaching the front sight typically requires a correctly sized hex nut driver. A dab of thread locker can prevent the sight from becoming loose with use. Aftermarket parts like a sight pusher tool can provide a more professional fit and are preferred by many gunsmiths. They should ensure the sights are aligned straight to maintain a consistent sight picture.

Rear sights may need gentle tapping or a sight pusher tool for precise placement. Throughout the installation process, one should check and recheck to ensure the sights are not canted and there is no damage to the sapphire window—if present.

Maintenance and Care

Maintaining Glock sights involves keeping them clean and remaining secure after installation. A simple cloth can wipe away debris without scratching the surface. For tritium or fiber-optic sights, it's essential to ensure the dot color remains vivid and is not obstructed by dirt or damage. Robust handling could dislodge the sights, necessitating checking that they have not become loose after every use. Applying a small amount of thread locker periodically can assist in keeping the sights firmly in place.

Troubleshooting Common Issues

A common issue with Glock sights is loosening over time, especially after frequent firing. If a sight becomes loose, it can often be tightened securely using the proper hex driver or applying a minute amount of thread locker. If a rear sight moves laterally in the dovetail, a sight pusher tool is recommended for re-adjustment. For more persistent issues or those involving the degradation of sight components, consulting a professional gunsmith is advisable, as they will have the expertise and proper tools to address the problem while ensuring the durable construction and integrity of the Glock is maintained.
